Abstract
A system including: a cable including: a core capable of transporting at least one useful electric signal; a sheath surrounding said core; at least one conductive wear detection strand embedded in the sheath and substantially extending along the entire length of the cable; and at least one reference conductive element which is not connected to said at least one wear detection strand and substantially extends along the entire cable length; and a control unit capable of measuring the capacitance or the resistance formed between said at least one strand and the reference conductive element.
Claims13
A system comprising:
- a cable (100;
- 200;
- 300) comprising:
- a core (101) capable of transporting at least one useful electric signal;
- a sheath (103) surrounding said core;
- at least one conductive wear detection strand (105;
- 205;
- 305) embedded in the sheath and substantially extending along the entire length of the cable;
- and at least one reference conductive element which is not connected to said at least one wear detection strand and substantially extends along the entire cable length;
- and
- a control unit (150) capable of measuring the capacitance or the resistance formed between the wear detection strand (105;
- 205;
- 305) and the reference conductive element.
A method of detecting the wearing of a cable (100;
- 200;
- 300) comprising:
- a core (101) capable of transporting at least one useful electric signal;
- a sheath (103) surrounding said core;
- at least one conductive wear detection strand (105;
- 205;
- 305) embedded in the sheath and substantially extending along the entire length of the cable;
- and at least one reference conductive element which is not connected to said at least one wear detection strand and substantially extends along the entire cable length, the method comprising a step of measuring the capacitance or the resistance formed between said at least one strand (105;
- 205;
- 305) and said at least one reference conductive element.
